32. Bronzed-metal mentalists Manowar claim to be the loudest band ever, for their perfomance of 139dB at 2008's Magic Circle Fest. Guinness World Records declines to recognise Manowar's claim, because it no longer includes a category of loudest band - Guinness says it does not want to encourage hearing damage. (Perspective? 120dB is the loudness of a transatlantic jet taking-off off at 200ft away. Most medics officially consider 130dB as "the threshold of pain").

33. The world's most expensive drumkit belonged to The Who's Keith Moon. His 'Moon The Loon's' custom-made 1968 Premier drum kit was auctioned off at Christie's in London in 2004 for $252,487.

46. Queen's Brian May solely used old-school curly guitar leads (cords) well into the 1990s. He favoured them because they reminded him of vintage telephones.
